Gold watch from The Babe

[b.heagy]

Looking for some help. I was introduced to a woman that had a gold pocket watch with the inscription "To Bumpy from Babe" Dec 25, 1937". She beleives it may have been a gift from Babe Ruth to his adopted daughter. She had this piece listed on ebay but at the time was unaware that it may be a Babe Ruth related item so it was not mentioned in the title or description. If this piece is legit how do you proove it would have come from Babe Ruth? Here are some pics from her original listings. These were only at 96 pixels when I copied them over so I hope they will be clear enough. I think its a great watch either way.
